I want to delete card in a RecyclerView after selecting it.data in the RecyclerView is JSON data
public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
if(response.isSuccessful()) {
JsonObject responseObject = response.body();
if (responseObject.has("data")) {
JsonArray arrayobject = responseObject.getAsJsonArray("data");
ArrayList<User_Details_Model> myorder = getGeneral(arrayobject.toString());
viewRequestControllerCallback.hitsuccess1(myorder);
Here is a good resource to detect which cardView is clicked. After clicking a cardView you can delete it:
Recyclerview-listener
public interface OnItemClickListener {
void onItemClick(ContentItem item);
}
public void bind(final ContentItem item, final OnItemClickListener listener) {
...
itemView.setOnClickListener(new View.OnClickListener() {
#Override public void onClick(View v) {
listener.onItemClick(item);
}
});
}
this is the adapter
public void onBindViewHolder(#NonNull final UserViewHolder holder, final int
position) {
final User_Details_Model product = user_details.get(position);
Log.d("######",user_details.toString());
holder.tv1.setText(product.getDriverId());
holder.tv2.setText(product.getDriverName());
holder.tv3.setText(product.getVehicleId());
holder.tv4.setText(product.getVehicleType());
holder.tv5.setText(product.getOilType());
holder.button_ok.setOnClickListener(new View.OnClickListener() {
#Override public void onClick(View v) {
int pos=holder.getAdapterPosition();
if (position==pos){
getdetails();
user_details.remove(pos);
}
}
}

I would like to get data from the box which click on on the recycler view to go into a another activity to display.
I have tried to flow this video https://www.youtube.com/watch?v=7GPUpvcU1FE&t=399s&ab_channel=PracticalCoding i dont understand at 6:16.
Also https://www.youtube.com/watch?v=VQKq9RHMS_0&ab_channel=Stevdza-San i cannot get the data to pass to the new activity.
Main code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_staff_home);
DB=new mainTextDBHelper(this);
recyclerView=findViewById(R.id.recyclerview);
Title=new ArrayList<>();
description=new ArrayList<>();
radiogroup=new ArrayList<>();
adapter=new recyclerviewAdapter(this,Title,description,radiogroup,listener);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
displaydata();
setOnClickListner();
private void setOnClickListner() {
listener=new recyclerviewAdapter.RecyclerViewClickListener() {
#Override
public void onClick(View v, int position) {
Intent intent=new Intent(getApplicationContext(),cardviewclickon.class);
intent.putExtra("Title",Title.get(position));
startActivity(intent);
}
};
}
private void displaydata() {
Cursor cursor=DB.getdata();
if(cursor.getCount()==0){
Toast.makeText(staff_home.this,"No Entry Exists", Toast.LENGTH_SHORT).show();
return;
}else{
while(cursor.moveToNext())
{
Title.add(cursor.getString(1));
description.add(cursor.getString(2));
radiogroup.add(cursor.getString(3));
}
}
}
recyclerview Adapter code
public class recyclerviewAdapter extends RecyclerView.Adapter<recyclerviewAdapter.MyViewHolder>{

If you want to pass data from one activity to other you can use PutExtra() method of the Intent class As I can see you are doing everything pretty much well but you have to catch these extra from the class you are passing like:- I want to pass data from recyclerView to CardViewClass I can do it like:-
In RecyclerView.java file:-
public void sendDataAndOpen(String title) {
Intent intent = new Intent(getApplicationContext(), CardViewClass.class);
intent.putExtraString("Title",Title); // You can use putExtra to put any datatype
startActivity(intent);
}
In CardViewClass.java file (Lets catch our passing data):-
public void onCreate(...) {
....
String title = getIntent().getExtraString("Title") // You can also use ExtraPut and // Must use Same Id
// Use data as you want
.....
}
I have Recycler ListView which I show in MainActivity and the first item it is as selected, I have done to click for another items but the last stays clicked and when I try to take this recycler view to show me in next Activity it doesn't work.
The first item it is selected but I have a click method which when click an image makes as selected but when I click a new image this works but the first item stays as selected so continues for others images. I want only a image to be selected.
I don't want to write twice the same code.
Is it good if I have a class only for this method which I can use everytime I want.
The id of recycler view list it is the same on both xml's.
If you have any suggestion for my question please let me know.
This is the adapter for the RecyclerView.

I have kind of to-do app. In profile activity, there are 2 tabs.
To-do and Done. In Tab 1, user can check as "done" of their "to-do". In this case, I want to update TAB 2's recyclerview.
I tried several things, but didn't work. Here is TAB 1 codes, it's almost same as TAB 2.
TAB 1 Class
public class Tab_Profile_1 extends Fragment {
private RecyclerView recyclerView_tab_todo;

If i'm reading this correctly, you have two tabs and a backend database that stores the to do items and their state? To get the second list to update, you just need to do the same thing that you're doing in your first list, and update the adapter's data set and notify that the data set changed. How you trigger this action in your second tab is really the question.
You can either use an interface and have your adapter notify your activity that recycler view 1 had an action on it, and you can then tell adapter 2 to update its data. You can either pass back the data and only notify one row, or you could notify the entire data set. If you're doing this all service based, you could just reload the recycler view from the service and it will have the new data.
I think all you need to figure out is how you want to notify tab 2 that it needs to update its data. My recommendation is:
public interface AdapterInterface
{
void itemCompleted(Item hereIsTheItemThatNeedsToBeAddedTo2);
}
Then inside your adapter have a property with getters/setters such as:
private AdapterInterface adapterInterfaceListener;
Inside your Fragment/Activity implement AdapterInterface and implement the itemCompleted function.
And then set your adapter.setAdapterInterfaceLisetener to that function that you implemented. Then inside your adapter when the user clicks the checkbook to mark it as done, you can call the adapterInterfaceListener.itemCompleted() function, and it will send that information to your Fragment/Activity. From there you can give that new data to adapter2, or recall the API, however you want to get the new data.
Does this help?
I am trying to add item from one adapter into another adapter. But when I added item, doesn't appear in the another adapter's recyclerview list.
ContactDataAdapter.java
#Override
public void onBindViewHolder(final ContactDataAdapter.ViewHolder holder, int position) {
holder.titleTv.setText(arrList.get(position).toString());
holder.conIv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CallFragment cf = new CallFragment();
//CallDataAdapter cd = new CallDataAdapter();
String t = holder.titleTv.getText().toString();
cf.addItem(t.toString());
//cd.addData(t);
Toast.makeText(view.getContext(), "Added " + t, Toast.LENGTH_SHORT).show();
}
});
}
CallFragment.java
public void addItem(String title) {
adapter.addData(title.toString());
//adapter.notifyItemRangeChanged(0,data.size());
}
CallDataAdapter.java
public void addData(String title) {
dataList.add(title);
notifyDataSetChanged();
notifyItemRangeChanged(0, dataList.size());
notifyItemInserted(pos + 1);
}
The Image that clicked added button
A list that diplay added item("asd" added from the beginning.)
First setup EventBus
Define events:
public static class MessageEvent {
public String title;
}
in CallFragment declare it
#Subscribe(threadMode = ThreadMode.MAIN)
public void onMessageEvent(MessageEvent event) {
adapter.addData(title.toString());
};
Register in your fragment from you setup ContactDataAdapter
#Override
public void onStart() {
super.onStart();
EventBus.getDefault().register(this);
}
#Override
public void onStop() {
super.onStop();
EventBus.getDefault().unregister(this);
}
Call the event
#Override
public void onBindViewHolder(final ContactDataAdapter.ViewHolder holder, int position) {
holder.titleTv.setText(arrList.get(position).toString());
holder.conIv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
MessageEvent event=new MessageEvent();
event.title= holder.titleTv.getText().toString();
EventBus.getDefault().post(event);
//CallFragment cf = new CallFragment();
//CallDataAdapter cd = new CallDataAdapter();
//String t = holder.titleTv.getText().toString();
//cf.addItem(t.toString());
//cd.addData(t);
Toast.makeText(view.getContext(), "Added " + t, Toast.LENGTH_SHORT).show();
}
});
}
I need to get informaions about item from recyclerView. I try do something like this to get in but this didnt work, any ideas?? I think that calling CheckBox is useless and i dont need it. but now i dont have any idea how to do it.
private void handlerForChannels() {
list = ChannelsManager.getInstance().getChannelList();
mAdapter = new SettingsCustomAdapter(context, posit, list);
verticalGridView.setAdapter(mAdapter);
textView.setText(R.string.title_channels);
button.setText(R.string.select_all);
final SparseBooleanArray mChecked = new SparseBooleanArray();
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mAdapter.getItemViewType(SETTINGS_CHANNELS);
mAdapter.getItemId(getId());
CheckBox cb;
int count = list.size();
cb = (CheckBox) view.findViewById(R.id.checkBox_for_recycle);
for (int i = 0; i < count; i++) {
mChecked.put(i, cb.isChecked());
}
mAdapter.notifyDataSetChanged();
}
});
button.setNextFocusLeftId(R.id.select_all);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
button1.setText(R.string.cancel_text);
button1.setNextFocusLeftId(R.id.select_all);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
((MainActivity) activity).closeSettingsDrawerFragment();
}
});
button2.setText(R.string.ok_text);
button2.setNextFocusLeftId(R.id.ok_button);
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
Add a new Array into your adapter with booleans, to set the checkboxes true or false:
//...
public ArrayList<Boolean> checkBoxesState;
//...
public mAdapter(Context context, ArrayList<String> posit, ArrayList<String> list, ArrayList<Boolean> checkBoxesState /* <- add this one*/) {
//...
this.checkBoxesState = checkBoxesState;
}
Than you set if they get checked or don't:
#Override
public void onBindViewHolder(final NotaViewHolder viewHolder, final int position) {
//...
viewHolder.checkBox.setChecked(checkBoxesState.get(position));
}
Now you probably already know how to check them but for those who stumble into this too, here's how:
//create adapter
mAdapter = new mAdapter(context, posit, list, checkBoxesStates /* <- fill with false booleans */ );
recyclerView.setAdapter(mAdapter);
//check them all
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for (int i = 0; i <= mAdapter.getItemCount(); i++) {
checkBoxesStates.add(i, true);
mAdapter.notifyItemChanged(0); //this updates the adapter
}
}
});
Edit:
You have to create your checkbox in the ViewHolder, something like this:
public class NotaViewHolder extends RecyclerView.ViewHolder {
//...
CheckBox checkBox;
public NotaViewHolder(final View itemView) {
super(itemView);
//...
checkBox = (CheckBox) itemView.findViewById(R.id.rowCheckBox);
//...
}
}
the best way to do this:
1. in your adapter add some code:
private boolean isAllCheckBoxSelected;
public void setAllCheckBoxesSelected(boolean isSelected){
isAllCheckBoxSelected = isSelected;
notifyDataSetChanged();
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
...
holder.mCheckBox.setChecked(isAllCheckBoxSelected);
...
}
2. in your fragment call where you need
mAdapter.setAllCheckBoxesSelected(true or false);
